You get precision engineering that delivers strength without excess weight. JT Sprockets combines computer-aided design with C45 steel and SCM415 chromoly steel alloy to produce a front sprocket that holds up to the demands of your chain drive. Heat treatment and beadblasting reduce material surface tension for durability you can count on ride after ride. Features C45 and SCM415 chromoly steel construction provides the strength needed for reliable power transfer Computer-designed profile optimizes the balance between weight and durability Heat-treated steel withstands the stress of acceleration and shifting Beadblasted finish reduces surface tension to resist cracking and wear Self-cleaning design sheds mud and debris to maintain consistent chain engagement
